Multi-package benchmarks: package names 'merged' in the result table

Hi,
When using JMH with benchmarks located in multiple/different benchmarks
the results are incorrectly merged together.
Here are some benchmarks from multiple packages:
package com.some.even.longer.word;
import org.openjdk.jmh.annotations.Benchmark;
public class SomeEvenMoreWeirdBenchmark {
@Benchmark
public void baseline() {
}
}
package my.sample.pkg;
import org.openjdk.jmh.annotations.Benchmark;
public class MySampleBenchmark {
@Benchmark
public void baseline() {
}
}
package test.jmh;
import org.openjdk.jmh.annotations.Benchmark;
public class TestJmhBenchmark {
@Benchmark
public void baseline() {
}
}
When I execute benchmarks I get the following results:
java -jar target/benchmarks.jar -f 1 -wi 0 -i 1
Benchmark Mode Samples Score Score error Units
t.j.TestJmhBenchmark.baseline.word.SomeEvenMoreWeirdBenchmark.baseline thrpt 1 3464644276.067 NaN ops/s
t.j.TestJmhBenchmark.baseline.baseline thrpt 1 3454747731.105 NaN ops/s
t.j.TestJmhBenchmark.baseline thrpt 1 3409380706.050 NaN ops/s
So instead of using package name from every benchmark class it seems that
"test.jmh.TestJmhBenchmark" is used as prefix for all benchmarks which is wrong!
Best regards,
